Does the unused postmeta affect the speed of my database? Anything in your database affects the speed of your database. The question is how much of a slowdown, and if the amount of data is significant enough. Unless your having a huge amount of metadata it will not affect the speed of your database very … Read more
I would suggest inserting your tours as posts (or custom posts) and using a custom reference table with the id matching the post id of the Tour post. You could use WordPress’s built in meta box functions to be able to edit each Tour in the edit posts page. You could update your reference table … Read more
Is it that your tags are being stripped, or that you aren’t preparing them prior to displaying them. Try wrapping your output: echo apply_filters(‘the_content’, get_post_meta($post->ID, ‘_custom_field_name’, true));
to store multiple values in same custom field key and print them at once If you want to store it as site option, you can use update_option() : http://codex.wordpress.org/Function_Reference/update_option Example 1: // some array to store: $items=array(‘yellow’,’orange’,’green’); // save the array update_option(‘myitems’,$items); // get the array $items=get_option(‘myitems’); // print the array echo “<ul>”; foreach($items as … Read more
Actually I’d love to have an answer from @ialocin, because he suggested me the way. But as the code is a bit long for comment field I’m posting it here as an answer. But I’d love to accept an answer more appropriate to the situation: After @ialocin’s suggestion, I got that, the $post_id wasn’t accurate … Read more
This is one way how to get the postmeta of the posts, by joining the postmeta table and fetching the _wp_attached_file meta value. Try this: $mydb->get_results( select a.*, thumb.meta_value from wp_posts a left join (select b.post_id, c.meta_value from wp_postmeta b, wp_postmeta c where b.meta_key = ‘_thumbnail_id’ and b.meta_value = c.post_id and c.meta_key = ‘_wp_attached_file’) as … Read more
Like @SamuelElh comment this is how I solved it: add_action(‘updated_post_meta’, ‘check_meta_change’, 0, 4); function check_meta_change($meta_id, $post_id, $meta_key, $meta_value) { if( ‘<ENTER YOUR META KEY>’ == $meta_key ) { // do stuff } }
Please see the Customize Posts plugin. It has a WP_Customize_Post_Setting and WP_Customize_Postmeta_Setting for representing posts and postmeta in the customizer, respectively.
Apparently in order to get the meta value right after saving the post, you have to either get the $_REQUEST[‘my_meta_value’] directly, or, if you need to update the database right away, you have to use update_post_meta() in your save_post action.
I got the solution so self-answering the question for future users/visitors. Hope it will help someone. I think this won’t be able to generate results based on the Post ID → the_post_thumbnail( ‘large’); However, this should work → <?php echo get_the_post_thumbnail($fpid, ‘large’); ?> (Above is succesfully tested) Other possibilities → <?php echo get_the_post_thumbnail($fpid, ‘thumbnail’); ?> … Read more
